我似乎无法在没有错误的情况下运行捆绑更新。我用Fedora 15和Mysql 5.5运行我的机器。
再次感谢，我为自己的无知而道歉;我是Rails的新手。
提前致谢！ ：）

看起来您应该在Gemfile中限制mysql2版本：
gem 'mysql2', '~>0.2.0'
[编辑] ...然后执行bundle install，当然
答案 1 :(得分：0)
正如我们在日志中看到的，我认为你已经在config / database.yml中指定了mysql作为适配器
将其更改为：
adapter: mysql2
编辑：
关于你的FormatError，我知道我必须使用：
bundle exec rake db:<command>
为了现在执行rake，你能尝试一下吗？
编辑2：
好吧，我建议您使用RVM来使用ruby 1.9.2设置项目。 Read RVM Doc可以轻松指导如何操作。
然后进行捆绑安装
之后，请确保：
ruby -v
它应该是1.9.2
然后重试你的db：像这样创建：
bundle exec rake db:create:all
希望它最终会奏效。 ; - ）

要删除rubygems弃用警告更新到最新的RubyGems版本并运行
gem pristine --all --no-extensions。
至于你的mysql错误。确保已启用MySQL服务/守护程序，并确保您的database.yml配置文件正确。
